Advertisements I've just started playing around with the TiVO network features on my series 2 DT and have gotten most of it working smoothly. However, I am having a strange issue with playback of converted avi files on the TiVO using Tivo Desktop Mac to transfer back. I am able to successfully convert the files using ffmpegx to mpeg2 (with a mp2 audio stream) at 544x480 and 4:3 aspect ratio. Some of these files are in 4:3 original aspect ratio, and some are in 16:9 aspect ratio, so I use the letterbox fields to add black lines to the top and bottom of these latter files. Encoding is 1024 to 1500Kb/s. The files convert successfully and appear to play normally on VLC, and the 4:3 files play fine on the TiVO (with some small clipping on the right and left edges, nothing to worry about). However, the files that were originally in 16:9 play very oddly, with heavy vertical lines in the image, graininess and a zoom in to the upper right corner of the image, as if its playing a much smaller resolution file. To test things, I created a TiVO compatible mpeg file from a 16:9 movie using VisualHub demo and it transferred and played fine. Now I have no problems buying VisualHub and using that for conversions - it's a great program - but I do want to know what I did wrong, because MediaInfoMac shows exactly identical settings for my files and VisualHub's files save for file size. Did I calculate the letterbox pixel sizes wrong, and would it cause this kind of error? (I calculate 87 now, but may have used 78 when encoding; I can't figure out how to check. What is the right size?) I can't see how, since the file ends up being 544x even if it stretches some due to miscalculation? Did I set something wrong in regards to aspect ratio? I can only seem to set resolution, and 544x480 does not equal 4x3. For reference, I have a 649 series 2 DT TiVO with a TIVO brand wireless adapter and a Powerbook G4 running OX 10.4.11. Any help would be greatly appreciated!
